To systematically evaluate the difference in leg length discrepancy (LLD) between robot-assisted total hip arthroplasty (THA) and traditional THA.
The Cochrane Library, PubMed, Web of Science, EMbase, CNKI, Wanfang, VIP, and CBM databases were searched by computer to collect cohort studies of robot-assisted and traditional THAs from inception to August 11th, 2021. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.3 software.
A total of 10 high-quality cohort studies were included. The results of Meta-analysis showed that compared with traditional THA, LLD after robot-assisted THA was smaller [ =-1.64, 95% (-2.25, -1.04), <0.001], Harris scores at 3 and 12 months after operation were higher [ =1.50, 95% (0.44, 2.57), =0.006; =7.60, 95% (2.51, 12.68), =0.003]. However, the operative time was longer [ =8.36, 95% (4.56, 12.17), <0.000 1], and the postoperative acetabular anteversion angle was larger [ =1.91, 95% (1.43, 2.40), <0.001]. There was no significant difference in Harris score at 6 months, amnesia index (Forgotten joint score, FJS), postoperative acetabular abduction angle, and incidence of complication between the two groups ( >0.05).
Robot-assisted THA is superior to traditional THA in postoperative LLD.
系统评价机器人辅助全髋关节置换术（THA）与传统THA在下肢长度差异（LLD）方面的差异。
通过计算机检索Cochrane图书馆、PubMed、Web of Science、EMbase、CNKI、万方、维普和中国生物医学文献数据库，收集自数据库建库至2021年8月11日关于机器人辅助THA与传统THA的队列研究。两名研究者独立筛选文献、提取数据并评估纳入研究的偏倚风险。使用RevMan 5.3软件进行Meta分析。
共纳入10项高质量队列研究。Meta分析结果显示，与传统THA相比，机器人辅助THA术后的LLD更小[MD=-1.64，95%CI（-2.25，-1.04），P<0.001]，术后3个月和12个月的Harris评分更高[MD=1.50，95%CI（0.44，2.57），P=0.006；MD=7.60，95%CI（2.51，12.68），P=0.003]。然而，手术时间更长[MD=8.36，95%CI（4.56，12.17），P<0.000 1]，术后髋臼前倾角更大[MD=1.91，95%CI（1.43，2.40），P<0.001]。两组术后6个月的Harris评分、遗忘关节评分（FJS）、术后髋臼外展角及并发症发生率比较，差异均无统计学意义（P>0.05）。
机器人辅助THA在术后LLD方面优于传统THA。
